Application filed July 16.190.7- Serial No. 384.093

e upper and lower separately connected, which arrangement To all whom it may concern:

Be it known that I, EDWARD D. SoHMIT'r, a citizen of the United States, residing at Brooklyn, in the county of- Kings'and State of New York, have invented certain new and useful Improvements in Sealing-Heads for Bottle-Sealin Machines, of which the followto repair thelnside mechanism, or in assembling the parts at the outset.

integral therewith a plurality, six, of radially arranged barrels, 5. eachhaving a bore 6 therein, for the reception of the devices which operate upon the slidable pins carried by the pl one of these devices will serve as adesciiption for the rest, as'said devices are identical in construction. These devices consist of a circular head 7 to which is connected a shank 8,'squared at its The squared portion passes through asquared opening- 10 in a nut 11, which construction prevents the devices from turning.

Interposed between the head 7 and the end 11 is a spiral spring 12, tending at all times to keep the device projected toward the plunger. Each head 7 is provided with anarrow extension 13 havin a bevel or cam surface 14 at its lower. end.

These extensions 13, when the and ride hlS invention relates to bottle sealing machines.

e invention contemplates a sealing head adapted for applying a sealing heads for adjacent to its mouth, and by indenting its flange at-intervals.

It will be understood that the head is commonly used in conjunction with a-suit able bottle support, which support is moved toward the head or the head moved toward the support to get the required sealing pressure. he movements of these parts may be brought about in any well known or suitable way, and as this invention does not reside in a mechanism formoving these parts, but in the head itself, only the head is shown,. which will be sufficient to enable those skilled in the art to understand the construction andoperation.

In the drawings: Figure 1 is a central vertical sectionalview of a head constructed invention, showing a bottle cap in dotted lines in the seal holding cavity of theplunger; Fig. 2 isa similar view of the lower part of a head, showing the upper-part of'a bottle within the'seal cavity, the position they assume. in looking the flange of the seal Fig. 3' is a detail perspective view of one of the devices for projecting the locking pins into the seal holding cavity to look the seal; Fig. 4 is a similar view of one of the slidable lock ing pins,--and Fig. 5 is a plan View of the locking said cap parts are assembled, extendinto in vertical grooves 15 in the outer face of the plunger 16. The plunger is ro-- 1ng oints 2-1 which, in the operation of the .hea engage and indent the flange of the seal into locking shoulder-on the bottle. Each pin is provided' on its upper side with a roove22, which receives and embraces the tion of a screw or threaded key 23, one of which is put into the plunger aboveeach pin. e recesses 17 are reduced at-their inner of the plunger. The plunger is reduced in diameter at its upper end as indicated at 25 and extends a proper distance into the upper art of the head casing, where its upper end ears upon the end wallof the cap 4,. a The downward movement of the plungeris limited by a ledge 27 formed on the lower head portion upon which ledge the plungernormally rests, as shown in Fig. 1.

outer face or periphery to receive an extension of the pin operating devices, the plunger being partly broken away to show one of the seal holding pins. Referring to the drawings, the numeral 1 designates the head, comprising in the main the upper part 2 and the lower' section 3. The part 2 is internally threaded as indicated 1 at 3' for the reception of the threads of a screw cap 4, and the lower art of thepart 2 seal holding cavity b any suitable means, but I preferably emp oy spring-backed pins unger.

parts are makes it easy to reach the interior of the head e lower part 3 of the head casing has f preferably engagement with the" locking ower por-' ends andopen into the seal holding cavity24 periphery of the plunger.

with their ends projected slightly cavity, such as are shown and In operation, when a bottle is in position to be sealed and the head moved down or the bottle moved up as the casemay be, the sealing spring will be compressed, ermitting the lunger to yield upwardly until the cam sur-' I aces 14 on the pin operating devices engage I 18, when the ebottle.

12, thus moval of thebottle from the head after it has rear ends of the seal locking been scaled, will force them-back in theirre- 'cesses in the plunger to,position to be again operated upon by the pin operating devices in the further operations of the machine. The screws 23' keep the pins jl8-from turning in their recesses, and insure the proper engagement between the cam surfaces 19 of the pins and the camsurfaces on the extensions of the pin operating devices.

Claims. v v

1. In a head for bottle sealing machines, a yieldingseal applying plunger aving a plurality of substantially radially arranged 're- 'cesses' therein, a slidable pin in each recess formed with a seal indenting point at its forward end and a cam surface at its rear-end, a plurality of laterally yielding devices independent of the plunger, each device havin a cam surface inthe'path of'move'men't of t e devices, whereby, when the dplunger is moved upward, the seal locking evices will be simultaneously vprojected forward to bring their seal indentdescribed in l my application Number 373,076, filed May they indent the flangle of the devices operate yieldingly e possibility of crushing" or within the 1 ing points into engagement with the flange of a seal to lock the same at intervals upon the lockingv shoulder of abottle.
